Ingredients

Ingredients:
– 3 pounds yellow onions (3-4 large onions)
– 3 tablespoons unsalted butter
– 1 tablespoon extra virgin olive oil
– 2 cloves garlic (minced)
– 2 tablespoons all-purpose flour
– ½ cup dry white grape juice
– 6 cups low sodium beef broth or stock
– ½ teaspoon salt (or to taste)
– ¼ teaspoon black pepper (or to taste)
– 4 sprigs fresh thyme (or 1 teaspoon dried thyme)
– 2 bay leaves
– 8 slices baguette
– 2 ounces Gruyere cheese (shredded)

How to Make French Onion Soup

Step 1: Slice the Onions

Slice the yellow onions into ¼-inch thick slices.

Step 2: Sauté the Onions

Heat the unsalted butter and extra virgin olive oil in a large Dutch oven over medium heat.
* Once melted, add the sliced onions.
* Cook while stirring every few minutes until they are very soft, browned but not burnt—about 25–30 minutes.
* Stir more frequently towards the end to prevent burning.

Step 3: Add Garlic and Flour

Add minced garlic and all-purpose flour to the pot.
* Cook while stirring for about 1 minute until fragrant.

Step 4: Deglaze with Grape Juice

Pour in dry white grape juice, cooking for an additional 1–2 minutes.
* Stir constantly while scraping up any browned bits from the bottom of the pot.

Step 5: Introduce Broth and Seasonings

Add beef broth, salt, black pepper, thyme sprigs, and bay leaves.
* Increase heat until it simmers, then reduce heat to maintain a low simmer.

Step 6: Simmer Soup

Let it cook uncovered at a low simmer for about 30 minutes, stirring occasionally.

Step 7: Toast Baguette Slices

While the soup simmers, preheat your oven to 400° F.
* Place baguette slices on a baking sheet.
* Toast in the preheated oven for about 5–6 minutes until golden brown on edges.

Step 8: Final Touches on Soup

Taste the soup; adjust seasoning with additional salt and pepper if needed.
Remove fresh thyme stems and bay leaves before serving.

Step 9: Prepare for Broiling

Preheat broiler to 425° F.
Place four oven-safe bowls on a heavy rimmed baking sheet. Transfer soup into each bowl.
Top each bowl with two toasted baguette slices (browned side down) and sprinkle shredded Gruyere cheese on top.

Step 10: Broil Until Golden Brown

Put the baking sheet with bowls under the broiler for about 2–4 minutes until cheese melts and lightly browns.
Watch closely to avoid burning!

Step 11: Serve Immediately

Serve hot! Garnish with additional fresh thyme if desired. Remember that the bowls will be extremely hot after broiling.

How to Serve French Onion Soup

French Onion Soup is a delightful dish that warms the soul. Serving it correctly enhances its rich flavors and comforting nature, making for a perfect meal on chilly days.

Use Oven-Safe Bowls

• Using oven-safe bowls allows you to broil the cheese directly on top of the soup, creating a deliciously melted layer that adds texture and flavor.

Garnish with Fresh Herbs

• Sprinkling fresh thyme or parsley on top before serving not only adds a pop of color but also enhances the aroma and taste of the soup.

Pair with a Side Salad

• A light side salad, such as a mixed greens salad with vinaigrette, complements the richness of the soup and adds freshness to your meal.

Offer Crusty Bread

• A side of crusty bread for dipping can elevate your French Onion Soup experience. It absorbs the broth beautifully and adds a satisfying crunch.

Serve with Cheese Platter

• A small cheese platter featuring various cheeses can be an excellent accompaniment, allowing guests to enjoy different flavors alongside their soup.

Provide Additional Seasoning Options

• Offering extra salt, pepper, or even some chili flakes gives guests the option to customize their soup to their liking for an enhanced dining experience.

How to Perfect French Onion Soup

Creating the perfect French Onion Soup requires attention to detail and technique. Follow these tips for an ideal bowl of soup.

• Caramelize Onions Slowly: Take your time when caramelizing onions for rich flavor. This process should take at least 25-30 minutes over medium heat for optimal sweetness.
• Use Quality Broth: A good quality low sodium beef broth elevates the overall taste. Opt for homemade if possible; it makes a significant difference.
• Toast Bread Properly: Make sure to toast your baguette slices until golden brown. This adds texture and prevents sogginess when placed in hot soup.
• Watch the Cheese Carefully: When broiling, keep an eye on the cheese to avoid burning. You want it melted and slightly browned for that perfect finish.
• Taste Before Serving: Always taste your soup before serving. Adjusting seasoning at this stage ensures maximum flavor in every bowl.
• Let It Simmer: Allowing the soup to simmer uncovered helps develop deeper flavors while evaporating excess liquid for a thicker consistency.
